Merge branch 'bc/hash-transition-16'
Conversion from unsigned char[20] to struct object_id continues. * bc/hash-transition-16: (35 commits) gitweb: make hash size independent Git.pm: make hash size independent read-cache: read data in a hash-independent way dir: make untracked cache extension hash size independent builtin/difftool: use parse_oid_hex refspec: make hash size independent archive: convert struct archiver_args to object_id builtin/get-tar-commit-id: make hash size independent get-tar-commit-id: parse comment record hash: add a function to lookup hash algorithm by length remote-curl: make hash size independent http: replace sha1_to_hex http: compute hash of downloaded objects using the_hash_algo http: replace hard-coded constant with the_hash_algo http-walker: replace sha1_to_hex http-push: remove remaining uses of sha1_to_hex http-backend: allow 64-character hex names http-push: convert to use the_hash_algo builtin/pull: make hash-size independent builtin/am: make hash size independent ...
